"In the history of religion, everybody knows big names like the Buddha, Jesus and Mohammed. Few people know the lesser names, and if you ask the average man on the street in the West, none will know the name Dirghatamas. Even in India, only a minority will know it. But, together with Yajnavalkya, first formulator of the all-important doctrine of the Self (Atmavada), Dirghatamas was one of the key thinkers of mankind."
